What produces the violent physical disruption of the surrounding environment released in an explosion? Explain how this creates shrapnel when a bomb explodes.
What will be an ideal response?
The sudden buildup of expanding gas pressure at the origin of an explosion produces the violent physical disruption of the surrounding environment. In a bomb, the extremely high pressure caused by the expanding gases pushes on the walls of the bomb, stretching and finally shattering them. The pieces of the walls are shattered and thrown outward in all directions by the force of the explosion, creating shrapnel.
